摘要： A sealing device for an oil rotary vacuum pump of the type which includes a rotor, a cylinder for accommodating the rotor, the cylinder having a suction port and a discharge port, an end cover provided at one end of the cylinder, a rotary shaft of the rotor passing the end cover, an oil casing attached to the end cover such that it encloses the cylinder, the oil casing containing oil, an interior of the oil casing above the oil forming a space portion, and a bearing provided in the end cover so as to rotatably support the rotary shaft of the rotor. The sealing device includes: a pair of sealing members mounted on a rotary shaft of the rotor and provided in the end cover, the sealing members being disposed separately from each other so as to form a gap portion therebetween, the pair of sealing members being located on the side of the bearing which is remote from the rotor; an oil reservoir portion formed between the bearing and the sealing member closer to the rotor in the pair of sealing members; a first passage for connecting the oil reservoir portion with the interior of the cylinder which is in the vicinity of the discharge port thereof; a lubricant disposed in the gap portion between the pair of sealing members; and a second passage for connecting the gap portion between the pair of sealing members and the space portion in the oil casing.

摘要： A fluid scroll machine whose movable scroll is balanced with a simple construction to decrease the weight and cost of the machine. Counterweights are attached to the peripheral portion of the movable scroll, and the thickness of the engaged portion of the scroll is reduced at the part of the portion, which does not participate in the compression of gas in the machine, so that the scroll is balanced with regard to the rotation thereof. The counterweights are attached to the movable scroll to increase the total mass thereof to balance the scroll. The thickness of the part of the engaged portion of the scroll is reduced to decrease the total mass thereof to balance the scroll. Therefore, the counterweights can be made relatively small.
摘要翻译：一种流体涡旋机器，其动涡旋机构采用简单的结构平衡，减轻了机器的重量和成本。配重附着在动涡旋盘的周边部分，并且涡卷的被接合部分的厚度在不参与机器中的气体压缩的部分部分处减小，使得涡卷平衡关于其旋转。配重附着在动涡旋件上以增加其总质量以平衡涡卷。涡旋件的接合部分的部分的厚度被减小以减小其总质量以平衡涡卷。因此，配重可以做得相对较小。

摘要： In an encased electric motor within a casing, an electrically insulating varnish is applied by vacuum impregnation to the inside surfaces of the casing and to the outer surface of the stator of the motor. The remaining empty space within the casing is filled with a heat conducting gas mixture comprising approximately 60-90% by volume of helium, with the remaining percentage being an electrically insulating gas having better electrically insulating properties than helium, such as sulphur hexafluoride. This encased motor is much lighter than conventional encased motors in which the stator enclosure is filled with a heat conducting resin potting compound and avoids warping damage which frequently occurs in conventional encased motors due to thermal expansion of the heat conducting resin potting compound.
摘要翻译：在壳体内的电动马达中，通过真空浸渍将电绝缘清漆施加到壳体的内表面和电动机的定子的外表面。壳体内的剩余空间填充有包含约60-90体积％的氦的导热气体混合物，其余百分比是具有比氦更好的电绝缘性能的电绝缘气体，例如六氟化硫。这种封装的电动机比常规封装的电动机要轻得多，其中定子外壳上装有导热树脂封装复合材料，并且避免了由于导热树脂封装材料的热膨胀而在传统封装的电动机中频繁发生的翘曲损坏。
